Title: Magnetic releasable fastener
Inventor: GADBOIS LAWRENCE D
IPC: F16B1/00
Filed: 1993-08-03
Abstract: ABSTRACT            A magnetic fastener is commonly known by it's function to solely fasten by an attracting magnetic field. To unfasten it's position must be done manually, mechanically and/or by an electromagnetic type device.   Therefore,  in a case wherein   super,  powerful, permanent magnets,  each having the capability of 300 pounds of holding force, are used it would be impossible to unfasten this type of fastener manually from its fastened position.        In this invention both attracting and/or opposing magnetic fields are used in an odd and/or even alignment of positive and negative magnetic  fields  to  determine  the  fastening  and/or  releasing position. This is accomplished by allowing radial movement between the insertion of a first member into a second member.   Each member has a proximal end of which attaches to a first and second object and each having a cylindrical body (ie. Male and Female) enclosing two half cylinder shape  permanent magnets symmetrically arranged within  their  own individual  distal  ends.  Because  of  their cylindrical nature and the radial movement allowed between them they are able to fasten and/or release from each other by radially turning the first member and/or second member into an attracting and/or opposing field.

Abstract: A novel cutting nozzle assembly for a postmixed oxygen-fuel gas torch is disclosed.  The nozzle assembly includes a cylindrical shroud which surrounds and extends away from the gas discharge orifices in the gas discharge end of the cutting nozzle.  The cylindrical shroud has the advantage of producing a tighter gas stream and of promoting a more thorough mixing of the preheat oxygen and the fuel gas to provide a hotter, more compact flame which produces a more parallel-sided cut through metal workpieces.  The cutting tip therefore conserves metal as well as cutting gases.  It also cuts faster than prior art postmixed cutting nozzles.
